Fermi Finds Previously Unseen Galactic Structure

NASA will hold a media teleconference at 2:30 p.m. EST on Tuesday, Nov. 9, to discuss a new discovery by the Fermi Gamma-ray Space Telescope. Gamma rays are the highest-energy form of light. The soon-to-be published findings include the discovery of enormous but previously unrecognized “gamma-ray bubbles” centered in the Milky Way.

Teleconference panelists are:

— Jon Morse, director, Astrophysics Division, NASA Headquarters in Washington
— Julie McEnery, Fermi project scientist, NASA’s Goddard Space Flight Center in Greenbelt, Md.
— Doug Finkbeiner, associate professor of astronomy, Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass.
— Simona Murgia, Fermi research associate, SLAC National Accelerator Laboratory in Menlo Park, Calif.
– David Spergel, astrophysicist, Princeton University, Princeton, N.J.

For dial-in information, journalists should e-mail their name, media affiliation and telephone number to Trent Perrotto at trent.j.perrotto@nasa.gov.
